BOTTLE AND STOPPER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 435,97 5, dated September 9, 1890.

Application filed Jan ar 22,1890. .Serial No. 337,695. (No model.)

To all whom it may concern:

Be it known that I, FRANK H. MOYER, a citizen of the United. States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Bottles and Stoppers Therefor; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to certain improvements, as hereinafter set forth, in the construction of bottles and in stoppers and caps therefor.

In the accompanying drawings, Figure 1 represents in side elevation, the upper portion of a bottle sealed in accordance with my present invention. Fig. 2 represents a vertical section thereof on the line a a of Fig. 1. Fig. 3 represents a side elevation, partly in section, of the neck of abottle constructed according to my present improvements. Fig. 4 represents a sectional elevation of my improved sealing and stopper inclosing and clamping cap separately. Fig. 5 represents an elevation, partly in section, of a bottle-neck of my construction provided with a protective thimble or ring. Fig. 6 represents a detail perspective View of my improved stopper minus the gasket or Washer. Fig. 7 represents an under plan view thereof. Fig. 8 represents a perspective View, and Fig. 9 a plan view, of the gasket or washer in itsnormal condition. Fig. 10 represents a plan view of said gasket or Washer in its compressed elongated form when in readiness to be passed over the bottom of the stopper-shank into position around the shank, as hereinafter explained.

Varied difficulties have been experienced in the construction and employment of bottles and stoppers and caps therefor in the efiort to secure a bottle that will withstand ordinary usage without chipping or breaking at the necktl1e most vulnerable point-in securing the actual and positive hermetic closure and sealing of bottles containing gaseous liquids, and in securing a stopper-ing and sealing device that can be readily and effectively operated and be at all times and under all circumstances reliable.

It is the object of my present improvements to produce a bottle that will be effectually protected from breakage in handling, transportatiomaud general usage at its weakest portionthe neckand one that in conjunction with my improved stoppering devices can be effectively and hermetically sealed at all times during transportation and handling.

I will now proceed to describe myimproved construction and arrangement whereby these important advantages are secured.

Referring to the accompanying drawings, 1 represents the neck of my improved bottle, which from the top rim down to the encircling bead 2 is encircled by a metallic ring or ferrule 8, for the purpose of protectingand strengthening the glass neck, which, as is well known, is the most vulnerable part of the bottle, as it is there that most breakages occur in the handling of bottles, and also for the purpose of aifording a metallic surface upon and against which the'enveloping cap may have bearing, it being well known in the art that where a metal surface (as a cap) is screwed upon or has frictional contact with a glass surface, such frictional contact with a glass often results in the chipping off and I breakage of the bottle. This ring or ferrule 3 is at its bottom edge provided with a depending lip or flange 4, which,'when said forrule is in position, is pressed within a notch or recess 5 in the head 2, whereby said ring or ferrule is held securely in position upon the bottle-neck.

For the purpose of more clearly showing the construction and adaptation for use of the bottle-neck andlthe stoppering devices,I have in Figs. 1, 2, and 3 omitted the neck-sheathing ring 3 and have shown its application in a separate figure, Fig. 5, alone.

Heretofore the necks of bottles have been provided with either a thread running in a single continuous line or with a thread having a plurality of convolutions, or with short ribs with more or less extensive spaces between, the result being either that insufficient bearing-surface has been provided for the cap to secure the necessary amount of gripping contact to insure the retention of said cap and consequently the stopper in perfect.

ly-locked position under rough usage, or else extra expense of construction, and extra 1abor has been involved in screwing and unscrewing the cap. To obviate these difificulties I form in the neck of my bottle a pair of cam-shaped or oblique threads or ribs 6 7, one of such threads commencing at -or about the center on one side of the bottle neck and extending downwardly in an oblique direction around the bottle to a position on the other side approximately, or nearly so, in a line vertically with the commencement of said thread on the first-named side of the bottle-neck, the other thread or rib 7 commencing at about the same position, but on the opposite side of the bottle, as does the rib 6, and extending partly around the bottle-neck in a similar manner to that described in referring to the rib 6. It will thus be seen that the respective ribs or threads 6 7 are practically semi-circumferential or half threads, each commencing and terminating on opposite sides of the bottle, a space 8 being left between the upper end of the thread 7 and the lower end of the thread 6, and also between the upper end of the thread 6 and thelower end of the thread 7 to permit of the ready entrance of the similarlyshaped and positioned threads 9 10 on the cap 11, to be presently more fully described. By this construction and arrangement of the threads or ribs 6 and 7, upon the cap 11 being dropped upon and over the mouth of the bottle the inwardly-extending threads or ribs 9 and 10 on said cap will immediately register with the threads 6 and 7 on the bottle, and immediately upon said cap being turned the threads thereon will engage the threads 6 7 and a steady gripping double and continuous bearing be afforded said cap by the said threads 6 and 7 entirely around the bottle-neck, which at once insures the firm clamping of said cap on the bottle. It will furthermore be observed that the respective threads 6 7 commence a certain distance below the rim of the bottle, leaving an unimpeded surface at the top of the bottle, and that there is a vertical space between the bottom edge of the metal cap 11 and the lower ends of the threads 9 1O thereon. These plane spaces at the top of the bottleneck and the bottom of the cap, respectively, permit of a sufficient amount of play and movement between the bottle and cap in sealing and unsealing, to prevent any danger of injury to the respective threads, which would be likely to result were said threads adjacent to the rim of the bottle and to the lower edge of the cap.

By constructing the cap with inwardly-proj ectin g threads 9 10 they have bearin g against the under side of the threadswn the bottleneck, and the entire strength of the doubled metal forming the cap threads is thereby utilized in withstanding the upward pressure of the gas in the bottle in contradistinction to where the cap has recessed threads or grooves 011 its inner face, in which latter case only the lower portion of the thread would be utilized to withstand the gas-pressure and in drawing the stopper down into sealing position, and unless such threads always precisely fitted the threads on the bottle-neck the sealing would be incomplete.

My improved stopper is formed with a head 12, having in its top face an upward swell or projection 13, upon which the top of the cap 11 bears, so as to insure the stopper being forced down in a-uniformly even direction in sealing thebottle.

14 represents a groove extending circumferentially around the side of the stopperhead with which an inwardly-projecting rib 15 in the head of the cap engages for the purpose of securing the stopper permanently within the cap. This groove 14, it will be noticed, is somewhat deeper vertically than is the rib 15, thereby permitting of a limited independent movement of the stopper within the cap, and also of the upward vertical movement of the cap, in the event of the cap springing up under pressure in sealing without coming in contact with the upper rim or bead a on the stopper and exerting a pressure thereon tending to loosen the stopper. The under face of the head of the stopper is slightly recessed to permit of the upper face of the elastic washer resting snugly therein.

16 represents the depending shank of the stopper. The lower end of this shank is on two sides beveled off, as at 17, and is of downward taper and oblong form, and is formed with ledges 18 18 on two opposite sides, upon which, as shown in Fig. 2, the bottom of the elastic washer rests.

19 represents the elastic washer, which has the customary central orifice 20, corresponding in circumference with that of the shank 16. By forming the lower portion of the stopper-shank of tapering and oblong form, as described, the circumference of which at its widest part equals the circumference of the stopper-shank, the elastic washer can be readily placed in and removed from position by simply compressing it sidewise into elongated or oblong form, as shown in Fig. 10, in which shape it can readily he slipped over the oblong lower portion of the shank onto the ledges 18 and around the rounded portion 16 of the shank, and as readily removed by a reversal of such movements.

The bottle-neck is formed of gradually-increasing thickness upward and to its rim, around the exterior edge of which is formed an upwardly-extending rib or flange 21, having a tapering inner wall 22 to facilitate the entrance of the washer. This rib or flange 21, in conjunction with the remaining portion of the rim of the bottle, forms an inner ledge or recess 23, immediately surrounding the bottle-mouth, upon and within which ledge and recess and overhanging the mouth of the bottle, the elastic washer rests and is compressed upon the cap being screwed home.

What I claim is 1. In combination, a bottle having on its neck a pair of semi-circumferential ribs or threads, and in the inner portion of its mouth rim a circumferential recess, a cap having inwardly-extending ribs or threads corresponding with the threads on the bottle-neck and terminating above the lower edge of the cap, and near its apex an inwardly-extending rib, a stopper having a shank and a head provided with an external circumferential groove,

with which the rib in the upper portion of the cap engages for the purpose of permanently retaining said stopper in said cap, and an elastic washer surrounding and having bearing upon said shank.

2. A combined bottlevand stopper therefor, consisting of a bottle having on the exterior of its neck'a plurality of semi-circumferential ribs or threads, each commencing on sides of the bottle opposite the one to the other, a suitable distance below the rimthereof and extending around to the opposite side of the bottle-neck, so as to constitute practically a single thread with dual upper and lowerbearings on opposite sides of the bottle-neck, and in its mouth-rim a circumferential recess encircling the mouth-bore, and an upwardly-extending flange or rib encircling the outer edge of the rim of the bottle-neck, a stopper having a depending shank, and a head having a circumferential groove in its outer edge and a swell or projection on its top face, an elastic washer encircling and having bearing upon the stopper-shank, and a metal cap having in its head an inwardly-projecting rib to engage with the groove in the stopper-head, and in its lower portion inwardly-extending ribs or threads corresponding with and adapted to engage the under faces of the ribs on the bottle neck.

3. In combination, a bottle having on its neck a pair of semi-circumferential threads, each commencing and terminating on opposite sides of the bottle the one to theother, the respective ends of said-threads being 1n the same vertical plane, a metal cap having similarly shaped and positioned inwardly projecting threads thereon terminating above the lower edge of the cap, astopper contained within and gripped by said cap, and having ashank and horizontal ledges at'the lower portion of said shank, and an elastic washer encircling the shank and resting upon the ledges thereon.

- 4. A bottle having a threaded neck and a lower vertically-slotted bead, and a metallic threaded neck protective ferrule or ring I adapted to cover said threaded neck, and having at its lower edge a dependinglip or tongue to fit within the slot in the lower bead for the purpose of securing said thimble from movement.

5. Abottle-stopper consisting of a head having a recessed under face, a shank having a tapering and oblong lower portion provided with oppositely-extendingledges, and an elastic washer encircling the shank and having bearing, respectively, thereon and Within the recessed head and upon the ledges on the shank.

In testimony whereof I affix my signature in presence of two witnesses.
